From my brakes. At first I didn't think the wheels would cause the brakes to squeak but the Brake guys couldn't find anything wrong. Has anyone ever experienced squeaky brakes after putting on new wheels?

 

I'm going to assume that you checked for rubbing and hitting and all that good stuff. If it isn't the telltale howl of the wear indicator on the pads touching down, then I would think you might need some anti-squeel compound on the back of the pads. The higher load of the larger rims and footprint is probably causing the pads to work harder and therefore moving around a bit in the caliper, resulting in squeeling. HTH
